1 Claim.

This invention relates to a device for sub-soil liquidY treatment orsaturation, and one of v its objects is to provide, improved means forvisibly discharging a suitable liquid on the faces of a furrow or trenchand surface which is being dug by a scarier or furrow-opening blade ofthe y device.

jects and advantages in view, this invention consists in the severalnovel features hereinafter fully set forth and more particularly definedin the appended claim.

The invention is clearly illustrated in the drawing accompanying thisspecification, in which:

Fig. 1 is a rear elevation of a device for subsoil liquid treatment orsaturation embodying a simple form of the present invention;

Fig. 2 is a side elevation thereof looking in the y direction of thearrow 2 in Figfl;

Fig. 3 is a front elevation of a modified form of scarifler blade;

Fig. 4 is a side elevation thereof; and

lFig. 5 is a plan thereof.

Referring to said drawing, the reference character 3 designates a toolstandard or arm of an implement to which is secured a scarifying orfurrow-opening blade 4 as by bolts and nuts 5. The implement (not shown)is provideed with a plurality of armsfand scarifying or furrow-openingblades for simultaneously digging a plurality of furrows or trenches inthe soil. The arms may be mounted on the frame ofthe implement, asshownand described in rmy prior application for patent, Serial No.793,200J filed December 22, 1947. The scarifying blade `l may be pointedat its top and bottom and is bowed rearwardly therefrom, as shown inFig. 2'.

Adjustably secured to the arm 3 is a liquid discharge or conducting tube6, to the upper end of which is secured a exible tubular connection 'lwhich leads from a suitable tank (not shown) for containing the liquidwhich is to be visibly applied to the faces of the furrow or trench. As

shown, the discharge or conducting tube is secured,v to the arm 3 by apair of U-shaped clamps 8, which extend around the arm and discharge orconducting tube with the ends of the clamps fastened upon the arm anddischarge or conducting tube by bolts and nuts 9, ortheir equivalents.

The lower end of the conducting tube 6 has a discharge opening I0 whichfaces rearwardly and downwardly and from saidlower end of the tube a lipIl extends rearwardly under said discharge opening which serves 'tospread or spray the liquid rearwardly and laterally towards the faces ofthe furrow or trench l2 prior to compaction or nlling in of the soil.The arrows I3 indicate the direction in which the liquid is spread bythe lip ll, and the lines I4 indicate the soil which has been turned upto form the furrow or trench.

In the modified form of scarier or furrowopening blade, shown in Figs. 3to 5 inclusive, the blade 4a is given substantially the same curvatureas that shown in Fig. 2. Adjacent its upper end, wings 4b extendrearwardly from the side edges and serve to temporarily hold back thesoil which has been thrown up by the blade, thereby retarding thefolding in of the soil until released by the wings, and giving longervisibility to the spray.

The device has many uses in the treatment of sub-soil, among which isroad building, preferably on sandy, wet soil. When used for buildingroads, oil is discharged upon the damp faces of the furrows or trenches,after which the lupturned soil is surface planed and compacted so as tomake a smooth pavement. Other uses are to stabilize dikes, like contourirrigation check; to make easy, cheap, deep, moisture-resistantcompaction; to plant remedies for plant enemies; to irrigate; to avoidevaporation loss; to plant liquid fertilizers; to plant liquidneutralizing alkalies; to plant liquids as, for example, crude oil forpermanently water-proong areas like fioors, walks, and pavements; formoistureproofing stock piles of soil for walls, roofsH of buildings, andthe'like; andv for moistureproong soil to be stock-piled fortransportation for such use as patching pavements and correcting grades.

With the use of the lip or spreader ll, the

liquid may be sprayed for paving, stabilization, Y

or for embankments to prevent washouts; also liquid saturation of soilagriculturally, such as sub-irrigation, etc.

Having thus described my invention, it is obvious that variousimmaterial modifications may ly vertical liquidconducting-1tube'havingiaf dis"` charge opening at its lower end, meansfor adjustably supporting said tube on therear-of"'saidA .arm ibehindsaid blade with; the lower4 end'fof: .said tube intermediate the ends ofsaid blade and ldisposed above the level of the normal soil"sur' :facewhen said vblade is in furrow-opening position, saidf dischargelopeningY facingt rearwardlyv and downwardly, andj a spreaderv includingav rearwardly extending'curvedilip fedf to the low -er'end of saidytubeunderand contiguoustosaid Idischarge openingA for-developing arearwardly :and 'laterally-1directedJspray-v from the liquid ^conductedby said tube for liquid treatment ofethe :faces ofA thefurrowrformed byf said:- blade; the
